What did you order?
Demand, supply, availability. Say you're a car dealer, if you want a VW you'll probably get it pretty quick (chip supply crisis aside); if you want a Mercedes Maybach S-class, you may have to wait a bit more...
With hi-demand rolex models you should receive something within a week, unless stock ran really low. This already changes with lower demand rolexes. I waited a fair amount of time for explorer 1 QC, for instance. If you asked for an A. Lange & Söhne tourbillon....
Be patient, QC will arrive. As already suggested, you can always ask for an estimate from your TD, but do not expect immediate answers, that can take its time, too.
Good luck!
